[0064] like Figure 2 As shown, the present invention includes a bearing assembly device, which includes: a steel ball storage structure 1, a steel ball supply structure 6, a bearing steel ball loading structure 4, and a component conveying structure 5; the steel ball storage structure 1 is connected to the steel ball supply structure 6 through a steel ball transmission hose 2, and the steel ball supply structure 6 is connected to the bearing steel ball loading structure 4 through the steel ball transmission hose 2, and the steel balls are introduced into the steel ball loading structure 4; the component conveying structure 5 conveys the outer ring N1 and the retaining frame N2 of the bearing to the bearing steel ball loading structure 4, and in the bearing steel ball loading structure 4, the steel balls are installed on the retaining frame N2.

[0065] like Figure 7 , Fig.13 The figure shows the schematic diagram of the ball supply structure, wherein Fig.13It is a structural schematic diagram of the shunting block 6-1 and the moving block 6-8 in section along the diameter of the goal hole 6-2 and the center line direction of the switch plug channel 6-10; the top and bottom of the shunting block 6-1 are respectively arranged in pairs with the goal hole 6-2 and the ball outlet 6-7 which are interconnected, and the goal hole 6-2 and the ball outlet 6-7 are connected through the ball falling channel; the goal hole 6-2 is connected to the steel ball storage structure 1 through the steel ball transmission hose 2.

[0066] A switch plug 6-5 is respectively provided at the bottom end of each ball outlet 6-7; each switch plug 6-5 moves horizontally along the bottom end surface of the shunt block 6-1 to block each ball outlet 6-7; in specific implementation, a switch plug spring (not marked in the figure) is provided at the end of the switch plug 6-5 away from the ball outlet 6-7, and the switch plug spring provides thrust to the switch plug 6-5 parallel to the bottom end surface of the shunt block 6-1. When there is no other external force, the switch plug 6-5 blocks the ball outlet 6-7 under the action of the switch plug spring.

[0067] The ball outlet adjustment device includes a ball discharge tube 6-3, a moving block 6-8, and a switch plug top outlet cylinder 6-6; a ball storage channel 6-9 is set inside the moving block 6-8 through the upper and lower end surfaces, and the number of steel balls stored in the ball storage channel 6-9 is the same as the number of mounting holes on the retaining frame N2 installed this time; all steel balls required for each steel ball installation operation are stored through the ball storage channel 6-9, and then put into the bearing steel ball loading structure 4 for installation. The bearing steel ball loading structure 4 does not need to set up a counter to count the steel balls, which simplifies the system structure.

[0068] The ball hole of the ball storage channel 6-9 is lower than the bottom end surface of the diverter block 6-1; the upper end surface of the volleyball tube 6-3 is lower than the bottom end surface of the moving block 6-8; the ball storage channel 6-9 and the volleyball tube 6-3 are located on the same vertical section; Fig.13 As shown, the top surface of the moving block 6-8 is parallel to the top surface of the diverter block 6-1, and the distance between the two is less than the distance of a steel ball, so as to avoid the steel ball from falling accidentally, and at the same time ensure that when the moving block 6-8 moves toward the switch plug 6-5, it can support the switch plug 6-5 and make it retreat.

[0069] In a specific implementation, a step bracket 6-10 including two step surfaces is set, the diverter block 6-1 is fixedly set on the highest step surface of the step bracket 6-10, the switch plug top cylinder 6-6 is movably set on the other step surface of the step bracket 6-1 through a slide rail structure, the moving block 6-8 is fixedly connected to the piston end of the switch plug top cylinder 6-6, and the volleyball tube 6-3 passes through the other step surface and is set vertically downward.

[0070] The ball-entry hole and the ball-outlet hole of the ball-storage channel 6-9 are not on the same vertical line. In this embodiment, the ball-storage channel 6-9 is an S-shaped structure. When the moving block 6-8 is in the default position, the ball-outlet hole of the ball-storage channel 6-9 is connected to the volleyball tube 6-3.

[0071] The movement direction of the piston end of the switch plug ejecting cylinder 6-6 is parallel to the movement direction of the switch plug 6-5; the switch plug ejecting cylinder 6-6 drives the moving block 6-8 to perform linear motion parallel to the movement direction of the switch plug 6-5; the moving block 6-8 is driven by the ball releasing linear module 6-4 to perform horizontal motion along the bottom end surface of the diverter block 6-1; in specific implementation, the ball releasing linear module 6-4 can be implemented based on an existing linear module, such as a linear module composed of a servo motor, a ball screw, and a screw pair.

[0072] When the ball needs to be discharged, the ball-releasing linear module 6-4 drives the switch plug to push out the air cylinder 6-6 and the moving block 6-8 to the ball outlet 6-7 of the corresponding size, and the switch plug to push out the air cylinder 6-6 pushes the moving block 6-8 along the bottom end surface of the diverter block 6-1 toward the switch plug 6-5 until the switch plug 6-5 is completely pushed open; the ball storage function is realized by setting a ball storage channel 6-9 in the moving block 6-8, and at the same time, it can play the role of pushing open the switch plug 6-5, and there is no need to set an electric opening device for the switch plug 6-5, which greatly simplifies the system structure.

[0073] When the moving block 6-8 is pushed toward the ball outlet 6-7, the ball outlet hole of the ball storage channel 6-9 is no longer connected to the ball volley tube 6-3. After the ball outlet 6-7 is connected, the steel balls discharged from the ball outlet 6-7 can be stored in the ball storage channel 6-9, ensuring that the ball storage channel 6-9 can be fully stored. After the ball storage channel 6-9 is fully stored, the switch plug pushes the cylinder 6-6 to drive the moving block 6-8 back, disconnecting the connection between the ball storage channel 6-9 and the ball outlet 6-7. After returning to the default position, the steel balls in the ball storage channel 6-9 are discharged along the ball volley tube 6-3. In the present invention, the structural design of the ball storage channel 6-9 is completely realized, and the switching connection between the ball outlet 6-7 and the ball volley tube 6-3 is realized without other switches. At the same time, a preset number of steel balls can be stored without a counter, which greatly simplifies the structure of the system. The steel balls fall into the ball storage channel 6-9 from the ball outlet 6-7, and are discharged into the bearing steel ball loading structure 4 through the ball volley tube 6-3 after being fully stored.

[0074] On the diverter block 6-2, different ball inlets 6-1 are provided according to the required diameter of the steel ball; the steel ball storage structure 1 is implemented based on the steel ball bottle, and steel balls of different sizes are stored in different steel ball storage structures 1, and each steel ball storage structure 1 is connected to a ball inlet 6-1 of the diverter block 6-2 through a steel ball transmission hose 2; when it is necessary to provide steel balls to the bearing steel ball loading structure 4, the ball discharge linear module 6-4 is started to drive the switch plug top cylinder 6-6 to move horizontally to the corresponding size of the ball outlet 6-7 to perform the steel ball discharge operation. The present invention realizes the ball supply operation of steel balls of different sizes by setting the diverter block 6-2. It ensures that the technical solution of the present invention can be applied to the assembly process of bearing steel balls of different specifications and sizes.

[0075] like Fig. 9 As shown, the feeding structure of the retainer N2 includes a retainer storage structure 7-1, a retainer transfer structure 7-2, and a retainer angle adjustment structure 7-3; the retainer storage structure 7-1 includes a retainer string rod 7-11, and a material guide channel 7-12 is arranged below the retainer string rod 7-11.

[0076] like Fig.10 As shown, the cage transfer structure 7-2 includes: a cage discharging bracket 7-27, a cage transfer cylinder 7-22, and a transfer plate 7-21.

[0077] The retaining frame discharging bracket 7-27 is arranged below the material guiding channel 7-12, and the transfer plate 7-21 is horizontally arranged between the retaining frame discharging bracket 7-27 and the material guiding channel 7-12; the length of the transfer plate 7-21 is greater than the diameter of the retaining frame N2, and a frame circular groove (not marked in the figure) is opened at one end of the transfer plate 7-21, and a flat channel opening baffle is provided at the other end; the height and diameter of the inner cavity of the frame circular groove are adapted to the retaining frame N2; a transfer guide rail 7-26 is arranged on the retaining frame discharging bracket 7-27, and the transfer guide rail 7-26 is horizontally arranged below the adjustment station 7-23 and the material guiding channel 7-12; the transfer plate 7-21 is connected to the transfer guide rail 7-26 through a slider rail structure, and the piston end of the retaining frame moving cylinder 7-22 is horizontally connected to the transfer plate 7-21; an angle measuring device is arranged above the adjustment station 7-23.

[0078] When it is necessary to feed the holder N2, the holder transfer cylinder 7-22 is started, driving the holder circular groove on the transfer plate 7-21 to the bottom of the material guide channel 7-12. The height of the holder circular groove is the height of a holder N2. When the holder circular groove is aligned with the bottom of the material guide channel 7-12, a holder N2 just falls into the holder circular groove; the holder transfer cylinder 7-22 is started, reversely started, and the holder circular groove is pushed to the adjustment station 7-23. The holder angle adjustment structure 7-3 picks up the holder N2 on the adjustment station 7-23 and performs angle positioning operation. The specific implementation is, Fig.10 On the transfer plate 7-21, a circular groove for placing a rack is arranged at one end near the adjustment station 7-23, and a flat channel opening baffle is arranged at the end away from the adjustment station 7-23. When the circular groove for placing a rack is pushed onto the adjustment station 7-23, the channel opening baffle blocks the lower outlet of the material guide channel 7-12. Through the setting of the transfer plate 7-21, it is ensured that one retaining rack N2 is taken out each time, and at the same time, it can meet the demand for the lower outlet of the material guide channel 7-12 when there is no need to take materials.

[0079] The angle measuring device in the present invention comprises: a laser rangefinder 7-25 and a positioning cylinder 7-24. Because when the steel ball is installed, when the retainer N2 is placed in the inner cavity of the positioning seat 4-1, the mounting hole needs to avoid the lower positioning tooth 4-132 in the positioning tooth mold 4-13, so before the retainer N2 is placed on the positioning seat 4-1, it is necessary to adjust the angle of the retainer; in the present invention, the laser rangefinder 7-25 detects the retainer N2 grasped by the retainer angle adjustment structure 7-3, and detects whether there is a mounting hole on the retainer N2 at the angle where the laser rangefinder 7-25 is located; if the detection result does not meet the preset, the retainer N2 is rotated by the retainer angle adjustment structure 7-3; in the present invention, a positioning cylinder 7-24 is also provided. When the laser rangefinder 7-25 detects that the retainer N2 meets the preset angle, the piston end of the positioning cylinder 7-24 is extended to physically confirm that the retainer N2 meets the preset angle, thereby ensuring that the retainer is placed on the positioning seat 4-1 according to the preset angle.

[0081] When it is necessary to pick up materials, the picking up and lifting cylinder 7-37 is started, driving the motor 7-35 for rotating the retainer to lower the picking up and tightening sleeve 7-32 until it reaches the preset height. The elastic tightening sleeve 7-321 is pressed into the inner cavity of the retainer by the picking up and lifting cylinder 7-37. The picking up and lifting cylinder 7-37 is started in the reverse direction to drive the retainer to rise to the detection height of the angle measuring device. When it is necessary to adjust the angle of the retainer N2 according to the detection result of the angle measuring device, the motor 7-35 for rotating the retainer is started, and the retainer rotates the active wheel 7-3 32 drives the holder rotating shaft 7-334 to rotate, and the holder N2 rotates to the preset angle. The angle measuring device detects again until the holder N2 meets the preset angle.

[0089] The inner and outer ring gripping structure includes inner and outer ring clamps and inner and outer ring feeding lifting cylinders arranged below the moving slide of the robot hand; the piston end of the retainer feeding lifting cylinder is vertically downward, and the inner and outer ring clamps are arranged at the end, such as Figure 8As shown, the inner ring loading and lifting chamber 5-5 and the outer ring loading and lifting cylinder 5-4, the piston end of the inner ring loading and lifting chamber 5-5 is fixedly connected to the inner ring clamp 5-6, and the outer ring loading and lifting cylinder 5-4 piston end is provided with an outer ring clamp 5-3; in specific implementation, the driving of the robot arm moving motor 5-1 for the robot arm moving slide 5-2 can be realized by existing technology, such as: through a screw slide guide module; in the present invention, there are three robot arm moving slides 5-2, corresponding to the grasping structures of the inner ring, the retaining frame, and the outer ring respectively, and the front and rear order of the slides is in accordance with the corresponding installation order of the bearings, such as in the present invention: three grasping structures are arranged in the order of the inner ring, the retaining frame, and the outer ring, and the components are also placed on the positioning seat 4-1 in this order; by adjusting the order of the slides, it can be ensured that the technical solution of the present invention is adaptable to different bearing assemblies.

[0090] like Figure 3 , 4 As shown, the bearing steel ball loading structure 4 provided by the present invention comprises: a loading structure arranged from top to bottom, a positioning seat 4-1, a loading lifting structure, and a loading rotation driving structure.

[0091] The inner cavity of the positioning seat 4-1 is provided with a lower positioning tooth mold 4-13, such as Figure 6 As shown, the top of the lower positioning tooth mold 4-13 is provided with a lower positioning tooth 4-132 along the circumferential direction, and the thickness of the lower positioning tooth 4-13 is adapted to the inner cavity of the positioning groove N22 at the bottom of the retaining frame N2; the distance between the lower positioning teeth 4-13 is not less than the diameter of the mounting hole N21 on the retaining frame N2, ensuring that when the positioning tooth 4-132 is inserted into the positioning groove N22, the retaining frame N2 can be positioned while not blocking the mounting hole N21, thereby ensuring that the steel ball can successfully enter the installation Hole N21; the inner cavity of the positioning seat 4-1 is an open cavity at the bottom, the height of the lower positioning tooth mold 4-13 is greater than the inner cavity depth of the positioning seat 4-1, and the lower positioning tooth body 4-131 at the bottom end of the lower positioning tooth mold 4-13 extends downward from the inner cavity of the positioning seat 4-1 and is arranged on the upper end surface of the ejection plate 4-15; an annular retainer support step 4-133 is arranged at the top end of the lower positioning tooth mold 4-13, and the bottom end surface of the placed retainer N2 is located above the upper end surface of the annular step 4-133;

[0092] A retainer supporting step surface (not marked in the figure) supporting the retainer N2 is provided at the top of the positioning seat 4-1. The combined shape of the retainer supporting step surface and the retainer supporting step 4-133 is adapted to the bottom end surface of the assembled retainer N2 and outer ring N1, ensuring that the assembled retainer N2 and outer ring N1 can be placed stably on the positioning seat 4-1, and the angle of the mounting hole N21 is vertically upward, ensuring that the ball injection port of the ball injection tube 4-4 can be aligned with the mounting hole N21, thereby ensuring that the steel ball injected by the ball injection tube 4-4 can enter the mounting hole.

[0093] The ball loading structure includes a ball injection tube 4-4, a ball pressing table 4-6, and an upper positioning tooth mold 4-11; the ball pressing table 4-6 is a conical cone with a narrow upper width and arranged vertically downward; the diameter of the cross section at the bottom end of the ball pressing table 4-6 is smaller than the inner cavity diameter of the retaining frame N2, ensuring that the ball pressing table 4-6 can enter the inner cavity of the retaining frame N2 when it descends; at the same time, the cross-sectional diameter of the ball pressing table 4-6 at the ball outlet of the ball injection tube 4-4 is larger than the inner cavity diameter of the retaining frame N2 minus the length of the steel ball diameter, ensuring that after the steel ball is injected into the mounting hole N21, a part of the steel ball is pressed inside the mounting hole N21, and the steel ball will not fall when the ball pressing table 4-6 rotates.

[0094] like Figure 4 , 5 As shown, the upper positioning tooth mold 4-11 is movably mounted on the upper tooth mold guide column 4-12, and the upper tooth mold guide column 4-12 is vertically fixed downward to the bottom end surface of the ball loading lifting plate 4-16; the outer periphery of each upper tooth mold guide column 4-12 is mounted with an upper positioning tooth buffer spring 4-12-1, and the two ends of the upper positioning tooth buffer spring 4-12-1 are respectively pressed against the top end surface of the upper positioning tooth mold 4-11 and the bottom end surface of the ball loading lifting plate 4-16.

[0095] The upper positioning tooth mold 4-11 is an annular structure, which is movably arranged on the outer periphery of the bottom end of the ball pressing table 4-6 through the upper tooth mold guide column 4-12; the bottom end of the upper positioning tooth mold 4-11 is provided with an upper positioning tooth 4-111 pointing vertically downward along the circumferential direction, and the distance between the two upper positioning teeth 4-111 located on the same diameter is adapted to the outer circumferential diameter of the retaining frame N2, ensuring that during the descent process, the upper positioning tooth 4-111 at the lower end of the upper positioning tooth mold 4-11 can be inserted into the position between the retaining frame N2 and the outer ring N1, and finally the upper positioning tooth mold 4-11 is pressed on the retaining frame N2 due to its own gravity. The upper positioning tooth 4-111 surrounds the outer wall of the retaining frame N2 from the outside; during the descending process of the ball loading lifting plate 4-16, the upper positioning tooth mold 4-11 descends accordingly. When the upper positioning tooth mold 4-11 is pressed on the retaining frame N2, the position of the upper positioning tooth mold 4-11 remains unchanged, and the ball loading lifting plate 4-16 continues to carry the ball pressing table 4-6 down until it reaches the preset position. In the technical solution of the present invention, through the setting of the upper positioning tooth mold 4-11, it is ensured that during the process of the ball pressing table 4-6 completely squeezing the steel ball into the internal process of the mounting hole N21, the retaining frame N2 will not fail to install the steel ball due to extrusion deformation. The upper tooth mold guide column 4-12 guides the upper positioning tooth mold 4-11, and the upper positioning tooth buffer spring 4-12-1 provides downward force to ensure that the upper positioning tooth mold 4-11 can be smoothly lifted and lowered along with the ball loading lifting plate 4-16, thereby avoiding the upper positioning tooth mold 4-11 from changing its angle during the lifting process, resulting in the upper positioning tooth 4-111 being unable to be correctly inserted between the retaining frame N2 and the outer ring N1.

[0096] The ball injection tube 4-4 is placed inside the ball pressing table 4-6 from top to bottom, the top of the ball injection tube 4-4 is connected to the ball supply device of the steel ball, and a curved pipe section 4-41 is arranged at the bottom, and the ball outlet at the end of the curved pipe section 4-41 is arranged on the side wall of the ball pressing table 4-6 and is parallel to the mounting hole N21 on the retaining frame N2; in specific implementation, a ball injection tube switch control cylinder 4-17 is arranged, and a ball injection tube plug (not marked in the figure) is arranged at the piston end of the ball injection tube switch control cylinder 4-17, and the ball injection tube plug is controlled by the ball injection tube switch control cylinder 4-17 to block or open the inner cavity of the ball injection tube 4-4, thereby controlling the timing of the steel ball in the inner cavity of the ball injection tube 4-4 falling.

[0103] The piston end of the retainer feeding lifting cylinder 5-9 moves vertically downward, driving the material taking expansion sleeve 7-32 to place the retainer N2 into the inner cavity of the positioning seat 4-1, and then the ejection cylinder 4-14 is started, and the piston end pushes the ejection rod 4-15 upward. The ejection rod 4-15 is ejected from the inner cavity of the positioning seat 4-1 from the bottom to the top from the center of the opening of the positioning seat 4-1, and is pushed against the center position of the elastic expansion sleeve 7-321. The expansion sleeve spring setting 7-323 is compressed inward, and the elastic expansion sleeve 7-321 shrinks inward and detaches from the inner cavity of the retainer N2; the material taking lifting cylinder 7-37 is started in the reverse direction, driving the material taking expansion sleeve 7-32 to rise, completing the separation operation of the retainer N2 and the material taking expansion sleeve 7-32, and the retainer N2 is retained in the positioning seat to complete the feeding of the retainer N2.
